Program 06: DYNAMIC OPERATING ENVELOPE (DOE)

The Dynamic Operating Envelope Programme sets limits on how much electricity can flow into or out of the network in a given area. These limits help the Electricity Distribution Business (EDB) manage local capacity safely and efficiently.

The EDB sends a signal to the flexibility supplier showing the maximum power levels allowed at certain points on the network. These levels can cover different times of day, such as peak, shoulder, and off-peak periods and may change depending on network conditions or local demand.

The flexibility supplier’s system then manages its connected devices or customers such as solar systems, batteries, or smart appliances to stay within those limits.

These limits may be:

  • Static: Where the same limit applies for a set period, or
  • Dynamic: Where limits change during the day as network conditions vary.

The EDB defines the setpoints, while the flexibility supplier uses its own energy management system to ensure all connected loads work together to stay within those limits.

Note: This programme is still being developed and will be expanded further in the next phase of FlexTalk.
